摘要

Whether they are analog, composite, component, or digital, today's video standards have emerged from the over sixty-year history of the television industry. Color cameras, frame grabbers, and displays use these standards as a basis for image capture, transmission, and display. These may include analog RGB, composite signals such as NTSC, PAL, and SECAM, or component signals such as YIQ. Over the next few years, however, these standards will be surpassed by digital video and transmission techniques that encompass the MPEG-2 standard. And, just as the synchronized oscilloscope gave way to the vectorscope and waveform monitor, digital standards will demand new methods of testing and new forms of test equipment.
